I can't agree the method you have described. A couple of reasons right off the bat.
Welding on cast iron. Yup, it can be done and done correctly---however,
it might break and where do you look for a repair/part?
Special parts. The 'inexpensive' way involves one off machine parts not found in any
junkyard, counter or catalog. Use as many stock parts as you can. If that is the way you
go, I believe it can be done as you described and be done safely.
The best two things I would recomend is spend $500 and put a small block gas GM or a GM
diesal in front of the stock T98, change the axle gears to 4.88 or depending on you
usuage. The stock transfer is Beefy. Straight cut gears which are darn near
indestructable BUT! The transfer howls like a homesick metal coyote if too much speed
is applied. The stock driveshafts are built heavy. There is a lot of room in a 715 and
one the best part of owning one is that so many stock assemblies bolt right on.
Jeep used the same basic cab-frame setup in their civilian truck line.
A stock heater, power steering, AC and seats, PTOs; the list goes on.
Good Luck,
